To all whom it may concern:

Be it known that l, Hnnnr TELLERS. a f

l H .1. eiproczne.

in the countv of Erie and State of Penns l- Y i vania, have invented a new and useful Pipetion.

D r seated upon the ends of the pass Organ, of which the following is a specifica- 1 This invention relates to pipe organs and sion of air to the pipe from the wind chest is under full control of the performer.

A further object is to provide means whereby the necessary grooving or channeling may be reduced to the minimum.

A further object is to provide a valve of I novel construction for each pipe, said valve being pneumatically operated in a simple and etlicient manner.

With these and other objects in view the l ll'lVGllDlOll COllSlStS Of certa1n novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim.

In the accompanying drawings is shown vation. Fig. 2 is a similar view of a portion of the wind chest and showing the valve open as when a pipe is being sounded. Fig. 8 is a plan view of one of the valves.

Referring to the figures by characters of reference, 1 designates a wind chest of the usual or any preferred construction and having a pipe board 2 thereon in which the pipes 3 of the organ are set, said pipes opening downward through the pipe board and into the wind chest. A valve seat preferably in the form of a ring a surrounds the inlet end of each pipe 8 and is designed to be contacted by a valve disk 5 carried by the upper face of a bellows 6 supported within the wind chest upon a bracket 7. A pipe 8 extends through each bracket 7 and opens into the bellows G thereon, said pipe extending through the wind chest and opening into one of the grooves or channels 9 such as ordi narily formed by registering channel portions for the purpose of conveying air.

-. outer end of pas This cha nel 9 opens into an air passage 10 in which a valve rod ll is mounted to re- Tliis rd has spaced valves 12 and 13 thereon des nod to be alternately e 10 so as to esta llSll communication between the channel 9 and either the exterior atmosphere or the interior of the wind chest. The valve stem ll is preferably actuated by means of a bellows 14 receiving air through. a channel 15, the admission of the air to the bellows being controlled by a key in any preferred manner. Each of the bellows 6 has a lifting spring 16 bearing upwardly upon studs 17 extending laterally from the top portion of the bellows, said spring being secured to the bracket 7 and one spring being arranged at each side or" each bellows.

l t is of course to be understoot that the wind chest i is designed to hold air under pressure and when the bellows l iis colosed as shown in l the top valve 12 is :ed and air under pressure free to pass channel 9 to the pipe 8 comminiicating the channel. The pressure of air \v 1 the bellows 6 is thus equal to the air we 'ire within the wind chest in which the bellows is mounted and tiiei-efore the spring 16 will be suiiicient to extend the bellows sin.

Pipe 3 will thus be held closed as indi- Fig. l. -When, however, is ctet. into the bellows ll so as to distcnd e valves 13 and 12 are shifted. Valve closes communication between the wind and the channel 9 while valve 12 communication between the channel he external atmosphere. The air contained within the bellows being thus relieved 0t pr sure will escape through the pipes 8 and channel 9 a be exhausted through the pressure of wind cl to collapse the surrounding an will thus cause the bellows 6 against the stress of soring l6 and a portion of the air within the chest will pass outward through the pipes 3 and sound them. The pipes can be promptly closed simply by a 'ain shifting the valves 12 and 13 so that air under pressure will be free to rush from the wino'chest into channel 9 and pipes 8 so as to distend the bellows 6 and promptly close the pipes.

It is course to be understood that the chan nels 9 are formed between grooved or chanthe wind chest through the passage 10 I channels have been shown with their face boards removed although a portion of one of these boards has been shown at 18 in Fig. 1.

In this construction it is possible to supply the wind promptly to the pipes and grooving and channeling is reduced to the minimum. This is due to the fact that the tubes or pipes 8 extend from the channeled boards adjacent the bottom of the wind chest directly to the valve bellows. For the purpose of re-adjustin the parts the channeled boards can be taken off by removing the screws or other fastening devices provided for them and the tubes or pipes S can then be lifted from between them.

lVhat is claimed is:

In an organ the combination with a pipe and a wind chest opening thereinto, of-a bracket supported within the chest, a bellows upon said bracket, a valve carried by the bellows and mounted on one face thereof, means for holding the bellows normally distended to hold the valve upon its seat to close communication with the pipe, an air channel, a pipe connection between said channel and the bellows, said connection be ing exposed within the wind chest and extending through the bracket and valve mechanism for controlling the movement of air within the channel and the pipe connection between the channel and bellows.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signa ture in the presence of two witnesses.
